To all whom it may concern; I

Be it known that I, Bonner E. :HAMMOCK, a citizen of the United States, residing at Allen, in the county of Pontotoc and State of Oklahoma, have invented certain new and useful Improvements in Rail-Fasteners, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to rail fasteners andhas for its object to provide a combined rail supporting chair and joint wherein the use of i'i'sh plates and connecting bolts through the web of the rail as is usually employed in devices of this character, is eliminated.

Another object of the invention resides in the provision of an improved rail fastener which will admit of the expansion and contraction of the rails due to changes in tem perature, but which will at the same time maintain the opposed ends'of the rails in alinement.

A still further object of the invention is to provide a rail fastener which is'simple in construction, may be easily and quickly applied to the rails and can be produced at comparatively small cost.

-With the above and other objects in view as will become apparent as the description proceeds, the invention consists in certain constructions combinations and arrange inents of the parts that I shall hereinafter fully describe and claim.

F or a full understanding of the invention reference is to be had to the following description and accompanying drawing, in which- Figure l is a perspective view of my irnproved rail fastener showing the same applied to the rails and secured. upon the supporting tie; Fig. 2 is a section taken on the line 22 of Fig. 1; Fig. 3 is a longitudinal section through the'side of the chair; Fig. 4 is a section taken on the line 4% of Fig. 3; and Fig. 5 is a detail fragmentary perspective view of one of the rails.

' Corresponding and like parts are referred to in the following description and designated in the accompanying drawing by like reference characters.

Referring in detail to the drawing 5 designates the adjacent rails to be connected and secured upon the supporting tie 6 by means of my improved fastener. The fa stening device comprises a chair plate 7 having a central depending enlargement 8. This enlarged portion of the chair plate '2' is adapted to be seated in a recess 9 provided in the supper surface of the tie. Upon the longitudinal edges of I inwardly extending flanges lO are formed for engagement upon the base of the rails 5. Longitudinal metal bars 11 are adapted to be arranged upon these flanges of the chair plate after the rails have been seated thereon. These bars are substantially coextensive in length with the chair plate 7. One of the bars 11 is provided upon its inner edge and centrally between its ends with a transversely disposed pin or lug 12 which is preferablyformed integrally with the bar. The other of the bars 11 upon the opposite side of the rails 5 is provided upon its inner edge with a socket or-recess 13 to receive the end of said lug. It will be noted from reference to Fig. 3 that the lug 12 is of octagonal form in cross section whereby the upper and lower inclined or beveled faces 12" are produced. The opposed ends of the rails 5 are provided in their web portions with recesses 14 which correspond in form to the cross sectional outline of one side of the lug 12, said recesses being provided with beveled or inclined walls 14. These inclined walls of the recesses in the rail webs areadap'ted'ito coact with the beveled faces 12f of the'lug 12 whereby, when the rails are in thir'normal positions upon the chair plate, the tread surfaces thereof are disposed in the samelongitudinal plane thereby presenting asmooth and unbroken bearing surface for the train wheels over the joint.

The base flanges of the rails 5 are provided in their edges with longitudinal recesses 15 with which spike receiving openings 16 and 17 in the flanges 10 of the chair plate and in the bars 11 respectively are adapted to coincide. The base or body portion of the chair plate 7 is also provided with openings through which the spikes indicated at 18 are adapted to be driven into the tie, thereby firmly and securely holding the chair plate in position upon the same.

By providing the elongated spike receiving recesses in the edges of thebaseflanges the chair plate 7 the en self the sails serves as additional supporting means for the rail ends and vents pounding ofithe same upon the 0 air plate when the-wheels pass over the joint.

At the same time, this lug will admit of the limited longitudinal'ior creeping movement. of :the' rails, but. 'eflectually prevent any,

relative verticalmovement thereof.

In assembling the device upon the rails,

the chair plate '7 is first moved inwardly upon'the end of one rail-and the other-,iall

is laid in position in alinement with the "first rail.

The chair plate 7 is then moved upon the latter rail until the same is disposed in the position shown in Fig. 1 of the drawing. Thechair plate is now arranged upon the tie with the projection 8 thereof seated in the recess of the tie and the bars 11 placed imposition. After the lug 12 on one bar has been inserted through the recesses in the l webs of the rails, and disposed in the socket ofthe other .bar, said bars and the chair plate are securely spiked upon the tie in the manner above described.

From the foregoing it is thought that the constructionand manner of application of my improved rail fastener will be clearly understood. The device is simple in construction, may be easily andq uickly applied and will at all times maintain the rails in proper alinement, and thus obviate serious accidents caused by the spreading of the rails.v

While I have shown and described the preferred construction and arrangement of the various elements employed, it will be understood that the invention is susceptible bf.,,., cons id,erable modification without departing from the essential features or'sacrificing any of-the advantages thereof.

Having thus described the invention, what is claimed' is:

'"1. The combination with mamas, of a chair plateupon which the same are adapted to be seated, said chair plate having inwardly extending flanges engaging over the base of the rails, a supporting tie provided wi-tha recess in its upper surface, said chair plate having an enlarged portion to be seated'in said recess, the base flanges of the rails havinglongitudinal .recesses in their edges, and longitudinal bars arranged upon the flanges of the chair plate on opposite sides" of therails, said bars and the chair plate having spike receiving openings coinciding with the recesses in the rail flanges, whereby the same may be secured upon the tie.

2. The combination with the rails having recesses 'in their abutting web portions, said recesses being provided with opposed inclined walls, of a chair plate upon which the rails are adapted to be seated, said chair plate having inwardly extending flanges to engage over the base of the rails, longitudinally extending bars arranged upon the flanges of the chair plate on opposite sides of the rails, a transversely disposed lug centrally formed upon the edge of one of the bars and adapted to be received in the recesses of said rails, said lug beingof poly onal form in cross section and provided with beveled faces toccact with the inclined walls of said recesses, and means for securing said bars and the chair plate upon the.

rail supporting tie.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
